Modular holster for a firearm

ABSTRACT

A module holster includes a shell module and at least one adaptor module. The shell module defines a first interior space configured to receive the slide of multiple different firearms, including a predetermined firearm. The adaptor module defines a second interior space with internal geometry configured to receive a trigger guard of the predetermined firearm. The adaptor module is longitudinally slidably engageable with the shell module to form a holster body. The holster body defines a cavity in which the predetermined firearm is removably receivable and from which cavity the predetermined firearm resists extraction. A user may slidably disengage the adaptor module from the shell module and replace it with a different adaptor module defining a second interior space with internal geometry configured to receive the trigger guard of a different predetermined firearm.

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of firearms, and more particularly, to holsters for firearms.

Gun holsters secure a firearm to a user's body for ready access and protect the firearm from inadvertent discharge, movement, damage, and loss. Rigid holsters made of synthetic polymeric materials are preferred by many gun owners over flexible holsters (whether made or natural or synthetic materials) because they better withstand heavy duty use in hostile environmental conditions.

However, many currently available synthetic holsters are equipped with rigid sections designed to fit one specific model of handgun. These rigid sections are typically molded to closely follow the exterior contours of the specific handgun and prevent the weapon from pivoting, rotating, and falling out of the holster. As a result, these rigid molded holsters are only usable with the specific firearm they were made to fit. This dramatically limits the usefulness of such holster and requires users to purchase a new holster for each different handgun a user desires to carry. Moreover, each new holster is likely to function differently in some way, including by requiring a different motion to remove a holstered firearm from retention, than a prior holster. Such difference requires users to learn how to use each new holster, which can in turn require different motions and thereby confuse users during combat situations where muscle memory and repeatability of motion is key to survival.

Accordingly, what is needed are improvements in holsters for firearms.

BRIEF SUMMARY

This Brief Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

Features of the presently disclosed invention overcome or minimize some or all of the identified deficiencies of the prior art, as will become evident to those of ordinary skill in the art after a study of the information presented in this document.

The present invention provides a modular holster that can accommodate, secure, prevent damage, loss, and/or inadvertent operation of different models of handguns using a universal rigid outer shell module and multiple interchangeable rigid handgun adaptor modules which are each configured with internal geometries selected to receive a different specific handgun yet mate with a resilient guide mechanism defined in the outer shell module.

The outer shell module is designed to receive the upper forward portion of multiple different handguns (e.g., the muzzle and a portion of the slide), while each handgun adaptor module is designed to receive the lower forward frame portion and trigger guard of a different predetermined handgun. Each handgun adaptor module is releasably yet slidably and matingly engageable with the same shell module. When a given adaptor module is engaged with the shell module, the two form a cavity in which a predetermined handgun is removably securable.

To secure a different handgun in the holster, a user need only detach the currently installed adaptor module from the shell module and reattach a different adaptor module configured to receive the desired handgun. This ability to use multiple different handgun adaptor modules to fit multiple different handguns within the same outer shell module represents a dramatic improvement over currently available holsters which accommodate only a single specific handgun. This reduces manufacturing costs and eliminates the need to obtain a different holster for each handgun in a user's collection. This in turn lessens the financial burden and learning curve placed on gunowners who wish to carry different handguns at different times by requiring that users purchase and learn the use of only a single easy-to-use holster system instead of one for each handgun.

Accordingly, aspects of the present invention provide a holster for a firearm comprising a shell module defining a first interior space configured to receive a slide of the firearm; and an adaptor module defining a second interior space configured to receive a trigger guard of the firearm; wherein the adaptor module is slidably engageable with the shell module to form a holster body defining a cavity in which the firearm is removably receivable and from which cavity the firearm resists extraction.

In another aspect, the invention provides a first body portion defining a first interior space in which a slide of the firearm is receivable, the first body portion including a primary left sidewall, a primary right sidewall, a front wall extending between the primary left and right sidewalls, and a pair of holes, each hole extending through one of the primary left and right sidewalls; a second body portion defining a second interior space in which a trigger guard of the firearm is receivable, the second body portion including a secondary left sidewall, a secondary right sidewall, a rear wall extending between the secondary left and right sidewalls, and a pair of threaded apertures, each threaded aperture extending through one of the secondary left and right sidewalls; and a pair of threaded fasteners; wherein the first and second body portions are slidably engageable along the respective primary and secondary left and right sidewalls to form a cavity in which the firearm is removably receivable and from which cavity the firearm resists extraction; wherein the holes in the primary left and right sidewalls align with the threaded apertures in the secondary left and right sidewalls when the first and second body portions are engaged; and wherein each threaded fastener is engageable with one of the threaded apertures through the respective aligned hole to releasably secure the first body portion to the second body portion.

Referring now to FIGS. 1 through 9, a modular holster 10 for a firearm constructed in accordance with an embodiment of the present invention is shown with a firearm 2 received therein. The firearm 2 is a handgun having an upper portion 1 a and a lower portion 1 b. The upper portion 1 a includes a barrel muzzle 3 extending out of a slide 4. A front sight 5 and a rear sight 6 are fixed to the top of the slide 4. The lower portion 1 b of handgun 2 includes a grip 7 and a forward frame portion 8 (which may be an accessory rail). A trigger guard 9 extends from the grip 7 to the forward frame portion 8 and surrounds trigger 9 a.

The assembled modular holster 10 includes a resilient first body portion 12 and a resilient second body portion 14 releasably and slidably engaged with the first body portion 12. The second body portion 14 is releasably secured to the first body portion 12 via a pair of threaded fasteners 16. The threaded fasteners 16 extend through and engage overlapping sidewalls of the first and second body portions 12, 14. A selectably tightenable fastener in the form of a Chicago screw having a male portion 18 a threadably engaging a female portion 18 b extends through the second body portion 14 and applies a frictional grip to trigger guard 9.

The first body portion 12 defines a first interior space 13 having internal geometry sized and shaped to receive the upper portion 1 a of multiple different handguns, including handgun 2. In the depicted embodiment, the upper portion 1 a of the handgun 2 received in the first interior space 13 is the muzzle 3, slide 4, and front sight 5. The second body portion 14 defines a second interior space 15 having internal geometry sized and shaped to grippingly receive the trigger guard 9 of a specific predetermined handgun, such as handgun 2. The forward frame portion 8 of the handgun 2 is also received in the second interior space 15. The second body portion 14 is slidably engaged with the first body portion 12 along a longitudinally extending handgun receiving and withdrawing axis 19. The combined first and second body portions 12, 14 form a substantially rigid holster body 11 defining a cavity 17 in which the handgun 2 is removably received and from which cavity 17 the handgun 2 resists extraction. The selectably tightenable fastener 18 a, 18 b can be tightened or loosened to increase or decrease the frictional grip that the second body portion 14 places on the trigger guard 9 while the handgun 2 is received in the cavity 17. In this way, retention of the handgun 2 in the cavity 17, and the corresponding degree of force necessary to extract the handgun from the cavity 17, can be increased or decreased to suit a user's preference.

The first body portion 12 is referred to herein as the “shell module” because the first body portion 12 is designed to function as a universal outer housing or shell in which the muzzle and/or slide of multiple different firearms is receivable and with which multiple different second body portions 14 are releasably and slidably engageable. Similarly, a second body portion 14 is referred to herein as a handgun “adaptor module” because each second body portion 4 is internally shaped and sized to receive and grip a different specific handgun. This design enables a user to use the same shell module with multiple different adaptor modules and quickly and easily swap out one adaptor module fitted to one handgun for a different adaptor module sized to receive a different handgun. The mechanism by which each adaptor module is slidably engageable with the shell module will now be described in detail.

Referring to FIGS. 10-13, the shell module 12 includes a first pair of opposing left and right sidewalls 20, 22 joined by front wall 24. More specifically, the shell module 12 includes a primary left sidewall 20, an opposing primary right sidewall 22, and a front wall 24 extending between the primary left and right sidewalls 20, 22. Each of the left and right sidewalls 20, 22 includes a respective opposing interior side 20 a, 22 a. The interior side 20 a, 22 a of each sidewall 20, 22 is a mirror image of the other. Defined on the interior side 20 a, 22 a of each sidewall 20, 22 is an inner mating rail 36 and an inner mating channel 38. The inner mating rail 36 is adjacent the inner mating channel 38. In this way, the inner mating rail 36 also in part defines the inner mating channel 38. The inner mating rails 36 have an upper end 44, a lower end 46, and a cross-sectional dimension 45 which increases along each rail 36 from the upper end 44 to the lower end 46. The cross-sectional dimension 45 can be a width or thickness of the rails 36. Similarly, the inner mating channels 38 have an upper end 52, a lower end 54, and a cross-sectional dimension 47 which decreases along each channel 38 from the upper end 52 to the lower end 54. The cross-sectional dimension 47 can be a width or depth of the channels 38. A first channel mouth 60 is defined in the interior side 20 a, 22 a of each sidewall 20, 22 at the upper end 52 of each inner mating channel 38. Each sidewall 20, 22 also defines a first channel stop surface 64 at the lower end 54 of each inner mating channel 38, as best shown in FIG. 13.

Turning to FIGS. 14-15, 17 and 29, the adaptor module 14 includes a second pair of opposing left and right sidewalls 26, 28 joined by rear wall 30. More specifically, the adaptor module 14 includes a secondary left sidewall 26, an opposing secondary right sidewall 28, and a rear wall 30 extending between the left and right secondary sidewalls 26, 28. Each of the left and right sidewalls 26, 28 includes a respective exterior side 26 b, 28 b. The exterior side 26 b, 28 b of each sidewall 26, 28 is a mirror image of the other. Defined on the exterior side 26 b, 28 b of each sidewall 26, 28 is an outer mating rail 40 and an outer mating channel 42. The outer mating rail 40 is adjacent the outer mating channel 42. In this way, the outer mating rail 40 also in part defines the outer mating channel 42. The outer mating rails 40 have an upper end 48, a lower end 50, and a cross-sectional dimension 51 which decreases along the rails 40 from the upper end 48 to the lower end 50. The cross-sectional dimension 51 can be a width or thickness of the rails 40. Similarly, the outer mating channels 42 have an upper end 56, a lower end 58, and a cross-sectional dimension 53 which increases along the channels 42 from the upper end 56 to the lower end 58. The cross-sectional dimension 53 can be a width or depth of the channels 42. A second channel mouth 62 is defined in the exterior side 26 b, 28 b of each sidewall 26, 28 at the lower end 58 of each outer mating channel 42. Each sidewall 26, 28 also defines a second channel stop surface 66 at the upper end 56 of each outer mating channel 42, as best shown in FIG. 17.

Referring now to FIGS. 20-22, 24-26, and 28-30, the adaptor module 14 is releasably slidably engageable with the shell module 12 along axis 19 as indicated by the arrow in FIG. 21. More specifically, the exterior side 26 b of the left sidewall 26 of the adaptor module 14 is slidably and matingly engageable with the interior side 20 a of the left sidewall 20 of the shell module 12, and the exterior side 28 b of the right sidewall 28 of the adaptor module 14 is slidably and matingly engageable with the interior side 22 a of the right sidewall 22 of the shell module 12. Even more specifically, the outer mating rails 40 are slidably receivable in the respective inner mating channels 38, and the inner mating rails 36 are slidably receivable in the respective outer mating channels 42 to matingly engage the sidewalls 26, 28 of the adaptor module 14 with the sidewalls 20, 22 of the shell module 12. When the outer mating rails 40 are received in the respective inner mating channels 38 and the inner mating rails 36 are received in the respective outer mating channels 42, the inner mating rails 36 interlockingly engage the outer mating rails 40, as best shown in FIG. 29. This interlocking engagement prevents the adaptor module 14 from separating rearwardly from (i.e., being pulled out the rear of) the shell module 12 during drawing of the handgun 2 and hard use situations when unexpected percussive forces can be applied to the handgun 2 or holster 10.

The first and second channel mouths 60, 62 facilitate sliding engagement of the adaptor module 14 sidewalls 26, 28 with the shell module 12 sidewalls 20, 22 by simultaneously aligning both the outer mating rails 40 with the inner mating channels 38 and the inner mating rails 36 with the outer mating channels 42. For example, during assembly, the lower end 50 of each outer mating rail 40 is receivable through the first channel mouth 60 to align the outer mating rails 40 for sliding engagement with the inner mating channels 38, and the upper end 44 of each inner mating rail 36 is receivable through the second channel mouth 62 to align the inner mating rails 36 for sliding engagement with the outer mating channels 42. The tapered cross sections of the inner 36 and outer 40 mating rails and corresponding outer 42 and inner 38 mating channels ensure fast mating and good alignment during assembly by indexing each mating rail into engagement with the corresponding mating channel and wedging them together in a self-holding taper fit. The inner 36 and outer 40 mating rails can be disengaged from corresponding outer 42 and inner 38 mating channels by sliding the adaptor module 14 upwardly relative to the shell module 12 in the opposite direction of the arrow in FIG. 21.

Referring now to FIGS. 11, 14, 20-22 and 28, each sidewall 20, 22 of the shell module 12 defines a hole 32 extending therethrough. The pair of holes 32 are laterally spaced and concentrically aligned. Each hole 32 is disposed above the inner mating channel 38 of the respective sidewall 20, 22 through which the hole 32 is defined. Similarly, each sidewall 26, 28 of the adaptor module 14 includes a threaded aperture 34 extending therethrough. In some embodiments, the sidewalls 26, 28 can define an opening 35 a in which a cylindrical insert 35 is permanently secured. In such embodiments, the threaded apertures 34 are defined through the inserts 35, as best shown in FIG. 22. In other embodiments, the threaded apertures 34 can be defined directly through the sidewalls 26, 28 without an insert 35. Threaded inserts 35 are made from a durable metallic material suitable for maintaining crisp threads over many use cycles. Suitable materials from which the threaded insert 35 can be formed include brass and steel.

Like the pair of holes 32, the pair of threaded apertures 34 are laterally spaced and concentrically aligned with each other. Each threaded aperture 34 is disposed above the outer mating channel 42 of the respective sidewall 26, 28 through which the threaded aperture 34 is defined. The apertures 34 of the adaptor module 14 concentrically align with the holes 32 of the shell module 12 when the lower end 50 of each outer mating rail 40 is received against the first channel stop surface 64 and the upper end 44 of each inner mating rail 36 is received against the second channel stop surface 66. Each threaded fastener 16 is receivable through one of the holes 32 and engageable with the respective aligned threaded aperture 34 to releasably secure the adaptor module 14 to the shell module 12. In this way, the stop surfaces 60, 62 serve to index the threaded apertures 34 of each adaptor module 14 with the holes 12 of the shell module, further simplifying holster assembly.

Referring now to FIGS. 12-13, 15, 21, and 23-26 the adaptor module 14 includes a tongue 72. The tongue 72 extends downwardly from the rear wall 30. The tongue 72 is recessed from an exterior surface 80 of the rear wall 30. The shell module 12 includes a rear shell wall 68 and a floor panel 74. The rear shell wall 68 joins the first pair of opposing left and right sidewalls 20, 22 opposite the first interior space 13 from the front wall 24. The floor panel 74 joins the sidewalls 20, 22, the front wall 24, and the rear shell wall 68. The rear shell wall 68 defines an exterior lip 76. The floor panel 74 defines an interior lip 78. The exterior and interior lips 76, 78, respectively, define a mating groove 70. The mating groove 70 is between the exterior lip 76 and the interior lip 78. The tongue 72 is received by the mating groove 70 when the adaptor module 14 is engaged with the shell module 12. The exterior lip 76 overlaps the tongue 72 and joins the exterior surface 80 of the rear adaptor wall 30 when the tongue 72 is received in the mating groove 70. Receipt of the tongue 72 in the mating groove 70 strengthens the connection between the adaptor module 14 and the shell module 12 and, like the interlocking inner and outer mating rails 36, 40, prevents the bottom of the adaptor module 14 from becoming dislodged from the shell module 12 when the holster 10 is subjected to percussion, whether via forceful insertion or withdrawal of the handgun 12 or other external factors such as combat conditions.

Turning now to FIGS. 8-12 and 27, the shell module 12 includes a muzzle guide 82. The muzzle guide 82 extends along an interior surface 85 of the front wall 24. The muzzle guide 82 extends longitudinally from an upper portion 86 of the shell module to a lower portion 88 of the shell module. The muzzle guide 82 is formed by a pair of parallel guide rails 90. The guide rails 90 are integrally formed with the interior surface 85 of the front wall 24. The guide rails 90 are laterally spaced so as to closely receive the front sight 5 of the handgun, as best shown in FIG. 29. The guide rails 90 capture the front sight 5 of the handgun 2 as the handgun 2 is inserted into the cavity 17 and prevent lateral movement of the slide 4 as the sight 5 travels through the muzzle guide 82, thereby aligning the handgun 2 with the cavity 17. This prevents the slide 4 of the handgun 2 from contacting sidewalls 20, 22 during and after holstering and thereby protects the handgun from scratches and other harm which might damage its finish.

Turning now to FIGS. 18A-19, the handgun 2 is retained in the assembled holster 10 by the adaptor module 14. The adaptor module 14 includes a pair of opposing left and right extension walls 92, 94, respectively, extending rearwardly from the rear wall 30. The left and right extension walls 92, 94 fully enclose the trigger guard 9 when the handgun is properly seated in the holster 10. Full enclose of the trigger guard 9 protects against accidental discharge of the weapon. The left and right extension walls 92, 94 each include an opposing interior side 96, 98, respectively. The interior side 96, 98 of each extension wall 92, 94 is a mirror image of the other. The interior side 96, 98 of each extension wall 92, 94 is shaped and contoured so as to grip the trigger guard 9 of the handgun 2. To that end, each extension wall 92, 94 defines a protrusion 100 on the interior side 96, 98 thereof. Each protrusion defines a vertex 102 and is a mirror image of the other.

When the handgun 2 is received in the cavity 17 with the trigger guard 9 properly seated in the second interior space 15, the trigger guard 9 sits below the vertices 102 of the protrusions 100 so that at least part of the protrusions 100 are received inside the trigger guard 9. The vertices 102 define between them a gap 103 which is narrower than a width of the trigger guard 9. As such, the protrusions 100 grip the interior of the trigger guard 9 and prevent it from being extracted from the second interior space 15 until an upward force sufficient to overcome the friction placed on the trigger guard 9 by the protrusions 100 and pull the trigger guard 9 through the gap 103 is manually exerted by the user along the handgun withdrawing axis 19.

The degree of retention placed on the handgun 2 by the holster 10 is controlled by the selectably tightenable fastener 18. A through hole 95 is defined through each extension wall 92, 94 below each protrusion 100. The female portion 18 b of the selectably tightenable fastener 18 is received through the hole 95 in one extension wall, while the male portion 18 a is received through the hole 95 in the opposing wall and engaged with the female portion 18 b. Tightening the fastener 18 drawings the male and female portions 18 a, 18 b closer together and increases retention by narrowing the gap 103 between protrusions 100, while loosening the fastener 18 decreases retention by widening the gap 103. In preferred embodiments, the fastener 18 is a well-known Chicago screw, but in other embodiments, a different selectably tightening fastener can be used.

The holster 10 of the present invention can be formed from any material of sufficient resiliency to maintain the handgun 2 in the cavity 17 while worn about the body of a user. However, it is contemplated that holster 10, including the shell module 12 and adaptor modules 14, will be formed from a molded synthetic polymeric material such as a plastic or a resin. It is further contemplated that the shell and adaptor modules 12, 14 will be injection molded. Therefore, in order to simplify manufacturing and decrease the costs thereof, the adaptor module 14 is designed with longitudinally drafted surfaces. These drafted surfaces enable the halves of a two-part injection mold to pull apart and release the molded adaptor module, which in turns allows for complete automation of holster 10 manufacturing.

Accordingly, the interior side 96, 98 of each of the left and right extension walls 92, 94, respectively, are longitudinally tapered about a parting line 104 by a draft angle 105 relative to a vertical reference plane 99. The draft angle 105 can be less than 5.0 degrees. In some embodiments, the draft angle is about 0.5 degrees. The interior side 96, 98 of each of the left and right extension walls 92, 94 is divided into an upper interior surface above the parting line 104 and a lower interior surface below the parting line 104. As such, the left extension wall 92 includes an upper interior surface 96 a above the parting line 104, and a lower interior surface 96 b below the parting line 104. Likewise, the right extension wall 94 includes an upper interior surface 98 a above the parting line 104, and a lower interior surface 98 b below the parting line 104. The parting line 104 runs laterally along the bottom edge of each protrusion 100, as best shown in FIGS. 18A and 19, and defines a reference plane 107.

Holsters 10 of the present invention can be readily configured for attachment to a user's body using any mounting device or mechanism known in the art. For example, such devices or mechanisms can be supported on the sidewalls 20, 22 of the shell module 12. Common mounting devices include belt loops and paddles, both of which are well known in the art, as are numerous methods by which such devices can be secured to a holster 10, including via fasteners, adhesives, sonic welding, and integral molding, among others.

Although embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that various modifications can be made therein without departing from the spirit and scope of the invention as set forth in the appended claims. For example, in some embodiments, the floor panel 74 and tongue 72 can be omitted from the shell 12 and adaptor 14 modules, respectively. This can be desirable for applications where the firearm(s) sought to be used with the holster 10 includes an especially long slide 4 or a muzzle accessory (e.g., a suppressor or muzzle brake) attached to the muzzle 3. In other embodiments, the firearm can be a different handgun, such as a revolver (not shown) or a large frame handgun such as an AR-platform pistol (not shown), all of which are well known. It is also contemplated that the holster 10 disclosed herein could be adapted for use with articles other than firearms which have a similar shape. For example, it is contemplated that tools such as cordless vacuums and caulking guns could be desirably secured in holsters of the present invention. Consequently, any two-module holster with releasably slidably engageable modules is considered to be within the scope of the invention.
